We would like to know if any of the CA common services components will be impacted by applying IBM APAR OA54807.
CA Common Servicse for z/OS r14.1 installed in a z/OS 2.1, 2.2,or 2.3 environment with IBM APAR OA54807 applied.
Software must no longer reference the IHAPSA field PSASTAK. With this PTF, PSASTAK is no longer the beginning of the normal FRR stack. PSACSTK is an existing pointer to the beginning of the normal FRR stack. Software that references PSASTAK must be converted to use PSACSTK as the pointer to the normal FRR stack.The PSASTAK is related to recovery management and the apar itself changes the definintion of the PSASTAK field in module IHAPSA to PSACSTK and software continuing to reference PSASTAK can receive a S0C4.
There are no Common Services components that reference or use the PSASTAK field so there is no impact.
